i have heard that you can burn an image onto a disk then format your hard drive put the cd in and it will restore the settings you put onto the disk back on the computer
no. An image is a bit level copy of your hard drive. I guess you could call an ISO an image, as it's the same thing, but it's not in this context. www.symantec.com
go there and look at the informaiton on Ghost. It's pretty straight forward.
I don't use drive image, but others do so maybe they can give you a link. I'm a ghost person.
